DEVICE FOR COOLING IVIOLDS.

SPECIFICATIONforming part of Letters Patent No. 628,543, dated J' uly 11, 1899. Application ned January 16,1399l sei-iai no'. 702,343. (No model.)

To @ZZ wtom/ t may concern: Be it known that I, JASON EVANS LIPPIN-V GOTT, a citizen of the United States, and a resident of Alexandria, in the county of Madison and State of Indiana, have in vented a certain` The object of my invention is to provide a` machine of this class in which the mold `can readily be immersed in and removed from water or other liquid, thus Acooling 'the mold and preventing burning of the interior lining of the mold.

It also relates to details` of construction hereinafter described and claimed.

In the drawings similar figures relate to similar parts throughout'the several views.

Figure l is a side and Fig. 2 a top View of my improved machine; Fig. 3, asectional side view on line 3 of Fig. 2. Fig. 4 is a plan View from line 4 of Fig. l. Fig. 5 is a side view taken on line 5 of Fig. 2, showing the cylinder partly in section'and the mechanism raised,

while Fig. 6 shows the same View, cylinderv not in section, with mechanism lowered. Fig. 7 shows a side sectional View through the center of the mold. Fig. Sis a side and Fig. 9 a central sectional View through the center of the three-way Valve. Fig. lO is a detailed View of the rod and pedal for operating the Valve. Fig. ll ris the same view as Fig. 3, showing the mechanism lowered into the liquid. Fig. l2 is a section, Fig. 13 a plan, and Fig. 14 a side view, ofsupport for the moldhinge. Fig. l5 is a top and Fig. 16 a side detail View of the mold.

In the drawings, 2l is a tank for water or other cooling liquid, of any convenient shape, mounted for convenience upon wheels 22, so that it may be drawn by handle 23 to any location desired. Rigidly secured to the bottom of the tank, at about its center, is cylinder 24, with its piston 25 and piston-rod 2G extending upward. To the upper end of piston-'rod 26 is rigidly secured the frame- 30, adapted gradually to check the fall of the cross-head (and platform 2S) upon the top of the piston. The platform 2S is strengthened by the truss-braces 3l on its under side and has holes 32 through itto allowfor the free passage of liquid. This platform might be supported by more than one cylinder without departing from my invention, and by making the tank deeper the mold might be mounted directly on the piston-rod without departing from the invention; but the construction shown has the advantage of enabling a more shallow and convenient tank to be used.

Rigidly secured to the platform 2S is a mold Vconsisting of a fiXedportion 33, havinghinged to it at 34 another movable part 35, held normally opened by springs 36. The mold-sections are lined with the paste lining ordinarily used in such glass-blowing molds. EX- tending from the iixed portion 35 is an arm 37, having thepin 3S rising from it. The hinge 34 of the mold is supported in the arms 39, attached to the upright 40, rising from the platform or table 23. The upper arm 39 may be adjusted up and down in the slot 4l of the upright 40, thus enabling diiTerentsized molds with different-length hinges to be substituted for the mold shown. On the opposite side of the table 28 is an air-tight box 2, which helps to displace the water in the tank as the apparatus is lowered into the water.

Mounted above thctank upon the uprights 29 is a working table 43, upon which the workman stands. Below this table, at 44, is pivoted a lever-arm 45, bearing at its outer end an upright rod 46, which extends up through and is adapted to move in a slot 47, cut in table 43. Pivoted to rod 46 is another lever, havin g an arm 43 extending upward and another arm 40 extending slightly downward. The lower arm 49 has a notch 50, adapted to engage with pin 3S 0n arm 37 of mold-section 35, and

the upper arm 43 is pivoted at its outer end 5l,

IOO

directly over notch 50, to a radial arm 52, havingl its center at 53 directly over the center of hinge 34. The radius of arm 52 being the distance from pivot 38 to hinge 34, the notch 50 and pivot 5l will move in a circle about the axis of hinge 34.

Connected to the lower end of cylinder 24 is an air or steam pipe 54, extending to ,a three-Way valve 54, mounted on the side of tank 2O and having the supply-pipe 55 and the exhaust-pipe 56. Pivoted to support 57 on the side of the tank is a -lever 58, having -pivotally connected to it at substantiallyT cylinder through pipe 56.

equal distances each side of the pivot 57 the vertical rods 59, which have at their upper ends the foot-pedals 60 and 6l. l The'lever 58 is pivotally connected bylever-arms 62 and 63 tothe valve 54, so that shoving down on pedal 60 will open the valve and admit steam from supply-pipe to the cylinder and stepping on pedal 6l will turn the valve so as to allow the steam to be exhausted from the cylinder through discharge-pipe 56.

In operating the machine the workman stands upon table 43 and presses pedal 60 downward, as shown in Fig. l. This admits steam, compressed air, or water pressure (whichever the manufacturer prefers) into the cylinder below the piston and puts the apparatus in the position shown in Figs. l, 3, and 5. He now takes an ordinary blowpipe, places the end of it, with a lump of molten glass on it, in the mold, and by pressing his foot against pin 46 (moving levers 45 and 48 to the position shown in dotted lines in Fig. 2) closes the mold. He now blows through the pipe and manipulates the glass in the usual manner until the article is properly formed and then withdraws his foot from rod 46,when, under the action of springs 36, moldsection 35 swings open to its iirst position and he removes the glass. The' tank having been filled with water or other cooling liquid, as shown in Fig. 3, the workman now steps on pedal 6l, thus throwing lever 56 to the position shown in dotted lines in Fig. l, which permits the steam or air toexhaust from the As this is done the table 28, bearing with it the molds and the box 42,settles into the water, as shown in Figs. 6 and l1, the pin 38 slipping out of notch 50. The mold being sufficiently cooled by the water, the workman steps on pedal and moves the lever 58 and the valve 54a back to the original position, as shown in heavy lines, Fig. l, thus admitting steam or air into the cylinder below the piston and forcing the table with the molds upward to their original position. The operation may then be repeated. By connecting pipe 54 to the upper end of the cylinder instead of to the lower and c attaching an air-pump the apparatus may be raised by pumping the air out of the cylinder and lowered by gravity.

Having thus described myinvention, what I claim as new, and desire to secure by Letters Patent, is-
